Introduction• “Accelerators Industry” includes all accelerator vendors who

supply entire accelerator machines for medical therapy , Irradiation, NDT and Ion Implantation. – Central facilities for users to do research works are not included.

– Devices at very low energy, such as x-ray tubes, electron microscopes or lithography systems are not included.

– The accelerator related technologies, such as rf tubes, modulators, magnets, vacuum devices, cooling system, ion and electron sources, beam diagnostic instrumentations, …, are not included.

– The accelerator users are not counted as “accelerator industry”.

• Asia is still importing lots of accelerators, for example, from VARIAN, SIEMENS, IBA, GE and so on. And most of them established accelerator factories in Asia. They are also not included here.

• Medical therapy , Irradiation and NDT are still the main applications of the accelerators in Asia.

• The vendor list is changing all the time.

Medical Applications

• Proton/Ion Radiotherapy

• Electron and X-ray Radiotherapy

• Radio-Isotope Production

Proton/Ion Radiotherapy

• Overall property of proton/ion radiotherapy – Because of the characteristic Bragg peak of proton and ion , proton or ion

radiotherapy permit one to control very precisely the shape of the dose distribution, and the dose delivered by a proton or ion beam can be well localized at the tumor.

– The proton/ion radiotherapy facilities are very expensive and need large space to install.

• Accelerators: – Cyclotron, synchrotron, ion linac, FFAG …

• Main Vendors in Asia: – Mitsubishi (JAPAN) , Synchrotron , Proton & Ion Therapy

– Sumitomo (JAPAN) , Cyclotron , Proton Therapy

– HITACHI (JAPAN) , Synchrotron, Proton Therapy, Ion Therapy (developing)

• Proton/ion Radiotherapy R&D in Asia: – HIMAC (Japan), Synchrotron, carbon beam

– Institute of Morden Physics (IMP) of China, Synchrotron, carbon beam

– Joint Institute for Nuclear Research (JINR) of Russia, Cyclotron, Proton

• The demands for ion radiotherapy are increasing fast in Asia.

Electron and X-ray Radiotherapy

• Most of the electron and x-ray therapy equipments are based on S-band rf linear accelerators. X and C band linacs can be more compact. X-band linacs have been used in Cyberknife and Mobetron. C-band is been developing.

• The products from VARIAN, SIMENS, ELEKTA still occupy a very large part of market in Asia. And they have branches in Asia.

• Main Vendors in Asia:– SHINVA (CHINA)

– HaiMing (CHINA)

– HITACHI (JAPAN)

– SAMEER (INDIA)

– NPKLUTS (RUSSIA)

Radio-Isotope Production• RI production for PET normally adopts 10-30MeV cyclotrons.

• The main vendors of the Cyclotron machines for RI production in Asia are – Sumitomo (Japan),

– Samyoung Unitech (Korea).

• R&D of Cyclotrons for RI production:– NPKLUTS (Russia )

– CIAE, IMP and CAEP (China)

ELV and ILU developed by BINP

Two kinds of widely used irradiation accelerators in Asia: ELV-DC high voltage

type, and ILU based on RF acceleration.

The electron beam power of ELV-12

can reach 400kW with electron energy

of 0.6-0.9MeV, and the electron

energy of ELV-8 can be 1.0-2.5MeV

with beam power of 90kW .

ILU covers the energy range from

0.6MeV to 5 MeV, and the maximum

beam power is 50 kW. A 5MeV/300kW

ILU accelerator is developing now.

Summary

• The accelerator industry in Asia is mainly at the area of medial therapy, NDT, irradiation and radioisotope production.

• New application area of accelerator means new market and new opportunity of accelerator industry. For example the cargo inspection.

• There are lots of accelerator facilities in Asia, such as synchrotron radiation light sources. They are playing an important role for developing new accelerator applications.

• For an accelerator, even a small one, is never a simple industry product, the academia-industry collaboration is always an essential issue for the accelerator industry.
